Discover the Mystery of the Underground River with the professor Karstix

We have created a teaching aid – the “Karstix and the Mystery of the Underground River” DVD that combines fun, education and a user-friendly interface to illustrate our educational programme.

Karstix will explain in his own words how the Hérault sinks into its bed, how caves are formed, and even the concretion deposit at Clamouse.
